| 31 | Tool bar | US203655 | 1998-12-02 | US6082467A | 2000-07-04 | Milford E. Friesen |
| A tool bar comprising an elongated tongue having a forward end rotatably secured to the hitch of a tractor and having first and second horizontally disposed pivot pins secured to the rearward end thereof at the opposite sides thereof. The inner end of a first elongated tool bar section is pivotally secured to the first pivot pin and a second elongated tool bar section is pivotally secured to the second pivot pin. The pivotal connection between the tool bar sections and the rearward end of the tongue permits the tool bar sections to flex upwardly and downwardly. The construction of the pivotal connection between the tool bar sections and the tongue is such that a flex-row averaging phenomenon occurs to prevent engagement of the gauge wheels of row planter units mounted at the center of the tool bar when the tool bar sections are flexed downwardly with respect to one another and which prevents engagement of the seed boxes on the row planter units located at the center of the tool bar when the tool bar sections are flexed upwardly with respect to one another. | ||||||

| 35 | Hitch construction | US3750759D | 1971-09-15 | US3750759A | 1973-08-07 | GEURTS C |
| A multi-bottom trailing plow is attached to the draw bar of a tractor. The hitch assembly of the plow includes a pair of vertical rods which are connected between a hitch plate fastened to the tractor draw bar and the plow frame. An expansion cylinder drives the frame relative to the hitch plate to adjust the vertical separation of the frame from the hitch plate and ground level. This arrangement also controls the depth which the plow bottoms penetrate the soil. A lever arm linkage extends from one of the vertical rods and to a tail wheel of the plow to provide for desired turning operation of the tail wheel of the plow. The hydraulic system for the expansion cylinder is controlled from the tractor. Thus, the position of the plow frame can be accurately and completely controlled to provide a level working depth by the plow bottoms.
